In this research, the winter wheat (Triticum aestivum L.) response to air temperature was investigated in Greece. Phenological observations were taken in order to evaluate the emergence (C0), heading (C1), anthesis (C2), fruit development (C3), and ripening (C4) phenophases of Triticum aestivum L. cv. Yecora at the sites (from Northern to Southern Greece) of Xanthi, Kozani, Karditsa, Thives and Araxos, during the period 1985-1990. Also, sowing dates and air temperature data were recorded at the same period. The warmer temperature conditions at the sites of Karditsa, Thives and Araxos promoted the reproductive growth phenophases of wheat (C1, C2, C3 and C4) compared to the respective conditions in Xanthi and Kozani. The C1 phenophase was influenced by the air temperature of the spring months (April and May) at the sites of Xanthi and Araxos. Air temperature during April and May plays an important role, to a different degree, for the C2 phenophase at the sites of the Central (Karditsa) and Southern (Thives, Araxos) part of Greece. |
